New standard actuators, are they readily available?
Posted 20 January 2011 - 03:02 PM
Can you guys please clarify this one for me please so I know exactly what all my options are before I shell out! Lastly where would be the best place to source o.e actuators ( assuming there available!) lotus factory themselves??
Sorry if ive asked this before (don't recall doing!)

The OEM ones are over £235 each x 2 = £470 which is why I used to supply the alloy ones. These are better, last longer and are half the price of the OEM ones. If you think of it as £115 each then they don't sound too bad.
I can still get them if you want them, drop me a pm. I gave a set of used OEM ones to North West Lotus about a month ago. You could try them if you can't afford new ones?
The part number is A918E6078S from Lotus or now the new number is C918E6078S

Standard T2 wastegate actuator
You will still need to re-use your screw-on rod and set-up the actuators to the Lotus mechanical boost setting.

Thanks to you both for the quick replies!!
Dave - if you can still get the alloy actuators then (pending the answers to the next questions) i'll probably be PM'in you soon to get some off ya buddy! Basically what i want to know is :-
1) Are these alloy actuators just a straight swap for the o.e items or do they require any "work" to get them to fit??
2) Are they "fit and forget" items too, As in are they pre-set to lotus o.e specs or will they need fitting and adjusting!???

They are a straight swap although because the OEM has floating bolts as opposed to the alloy actuators with fixed bolts, sometimes you have to drill the holes to one of your brackets to the next size up. When I fitted mine they went straight on but some owners experienced problems and had to open up their mounting holes. Only took another 5 mins.
As for setting up, providing you go for standard springs then the setup is the same as the Lotus technical manual.
Mike's Ebay link looks like a good buy too, so check it out and do you sums before buying. The Fiesta ones are ever so slightly different to the Lotus one whereby you have to kink the actuator rod a bit more. Sometimes you can get away with no alterations at all.

Will the setup require purchasing any special tools??
Old actuators are well knacked, and atleast one may well have not been working at all recently as the diagphram looked to have gone!

We've got the alloy actuators fitted in place, and have roughly "guessed" how to set them (the rod end is adjusted so it's "just" holdding the wastegate shut! - or so we think anyway!
I tried without luck to source a hand pressure pump with gauge yesterday so we could pressurise the capsule with 5psi and see if the actuator rod moves, but tbh I have no idea "how much" it's supposed to move when it does, and what the correct procedure for setting them up is anyway!
If we get done today i did have plans on taking the car out and gingerly winding her up bit by bit to see what boost levels we hit, but even if we do manage 0.35bar or whatever it's supposed to be, then were not gonna know whether that's balanced across both sides equally or not!
Push comes to shove i'd like to think i could actually drive the car to a specialist and get the wastegates properly setup there - just to be sure!

Someone desperately needs to get themselves and owners manual
To set the wastegates up for the correct mechanical base boost, you will need a dial gauge and some way of apply calibrated pressure to the wastegate capsule.
Make sure that you have the standard green spring fitted in the aftermarket wastegate capsules.
You will be looking to position the dial gauge rod horizontally along the direction of the actuator arm. You´ll need to fit the dial gaugein position to accurately measure the movements. Oncee in position, zero the gauge and start to apply pressure slowly to the capsule. Adjust the length of the wastegate actuator rod (1/2 turn increments), until you have 0.4mm (0.015") with 4.9-5.2psi.

You're right i suppose i could do with getting hold of a w/shop manual, But due to the fact that i'd have to buy new kit to set the actuators up i think i'm gonna simply take the car to a specialist n let them do it!
